Dx51d Equivalent Z100g Regular Spangle Gi Steel Coil
Product Description
Galvanized coil, the thin steel plate is immersed in the melting zinc tank, so that the surface of the thin steel plate with a layer of zinc. The main use of continuous galvanizing process production, that is, the rolling steel plate is continuously immersed in the melting zinc plating tank made of galvanized steel plate; Alloyed galvanized steel sheet. This steel plate is also made by hot dipping, but immediately after being taken out of the tank, it is heated to about 500 ° C to form an alloy film of zinc and iron. This galvanized coil has good coating tightness and weldability.

There are many factors affecting the size of zinc flowers. When the zinc liquid composition has the conditions for the formation of zinc flowers, the following factors will affect the size of zinc flowers:
(1) Raw material: the thicker the raw material steel plate, the smaller the surface roughness, the larger the zinc flower.
(2) Cooling rate: the faster the cooling rate, the shorter the crystal growth time, the smaller the zinc flower.
(3) Number of crystal nuclei: The size of zinc flower is closely related to the number of crystal nuclei of zinc flower. When the surface of steel base is rough or the surface cleanliness is poor, the zinc flower is relatively small. Zinc grains are formed on steel base, and the more nuclei there are, the smaller the zinc flowers will be. This principle is used in the production process of small zinc flowers.
(4) Other factors (production environment, etc.).
